IMPROVEMENT IN FLOUREBOLTS.

Specification forming part of Letters Patent No. 50,371, dated October 10, 1865.

To all whom it may concern:

Be it known that I, S. LEWis, ot' Tifin, in the county of Seneca and State ot' Ohio, have invented a new and useful Improvement in Mill-Bolts and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 is a top view, showing my invention applied to the reel of a mill-bolt, the cloth being removed. Fig. 2 is a vertical section looking toward one end of lthe reel. Fig. 3 is a vertical section looking toward the opposite end ofthe reel. Fig. 4L is an elevation of one end of the case of the bolt, showing the contrivance for adjusting the tripping-pin of the hammers.

This invention relates to an improved arrangement and mode of operating hammers which are applied within the bolting-cloth of a bolting-mill so as to turn with the reel, whereby a person can regulate the force of the blows ot' these hammers or stop their operation at pleasure without stopping the motion of the reel, as will be hereinafter described.

To enable others skilled in the art to understand my invention, I will describe its construction and operation.

In the accompanying' drawings, Arepresents the reel-shaft, which has its bearings in the ends of a casing, which may be constructed in any ofthe well-known ways. From this shaft project radial arms B B, to the ends of which longitudinal strips C C are secured,which may be braced by a hoop, a, in the center, so as to maintain their parallelism to the central shaft, A. Over this reel, which may be constructed and arranged in any suitable manner, the bolting-cloth is stretched, (which is left off in the drawings for the purpose of exhibiting the hammers that are arranged within the reel.) On the inside of each one of the longitudinal strips or stretchcrs O a rod, b, is pivoted, which has one end bent at right angles to itself, as Iindicated at b', Figs. 1 and 2. This rod b has a spring-arm affixed to it, as shown at c, Figs. 1 and 3, which spring presses upon the shaft A. Two or more hammer-rods, d d, also project from the rod b, and carry on one end the hammers e c, which have depressions formed in their ends that receive pins or anvils g g, that are affixed to plates on the rod or strip which is next the one to which the hammers are pivoted. These hammers are held in contact with their respective anvils by means of the spring c, so that the reel maybe rotated without actuating them-t'. c., causing them to strike. When the hammers of the several rods b are held in contact with their anvils, as shown in the drawings, Figs. 2 and 3, the angular arms b all point inward toward the central shaft, A, so as to successively come in contact with a pin, h, that projects through one of the headsofthe case D, as shownin Figs.

1 and 2. This pin operates to trip the arms b and to move the hammers back a greater or less distance from their anvils and then release them7 so that the springs c will return. them forcibly against their an vils, thus giving the desired concussion or jar to the boltingcloth. The pinv 7L passes freely through a curved slot which is made through one of the heads of the case D, and is secured to a segment, E, that is pivoted concentrically to said slot outside of said casing, as shown in Fig. 4. Below the pivoted segment E is a handle, F, which is free to rotate, and which receives a band, g4, that passes over the segment. By turning' said handle slight-ly the pin h may be moved toward or from the axis of the reel, and thus the length ot' stroke of the hammers can be in creasedor diminished atpleasure, whether the reel be in motion or at rest. By moving the pin h so near the shaft A that the arms b will not impinge upon it when the reelrevolves, the hammers will not be lifted from their anvils, and ot' course the reel-bolt or boltingcloth will receive no jar.

I do not contine my invention to any par ticular arrangement ofthe hammers, nor to the device for adjusting the trippingpin It, although I have described the most preferable plans, as it is obvious that the hammers or rappers may be arranged in many different ways, and the force of their blows regulated by a device operating substantially as described and arranged outside ofthe reel.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. Applying and actuating hammers or rappers which are arranged within the reel of a bolting-mill in such manner that the force of the blows of said hammers can beincreased or a bolting-reel and a device which is arranged diminished at pleasure, whether the reel be in outside of said reel for regulating the force of motion 0r at rest, substantially as described. the blows of the hammers, as wellas stopping -2. The employment of springs applied to i their operation altogether, substantially as dehammers which are arranged within the reel scribed. of a bolting-mill for the purpose of increasing S. LEWIS. the force of the blows oi' said hammers, sub- Witnesses: stantially as described. A. H. BYERS,
